For Lafayette, Zillow reports a typical city home value of $228,144 and typical observed market rent of $1,324 a month. Their direct ratio is a 7.0% gross yield before vacancy, management, maintenance, insurance, taxes, utilities and financing. As cross-source affordability screens, the home value equals 3.7x ACS city median household income, while annual Zillow rent equals 25.7% of that income. These ratios frame top-line economics, not a net return or household-specific affordability test.
The ACS describes 59,363 city housing units, with a 10.8% vacancy rate and renters occupying 46.9% of occupied units. Its $257,000 median home value is owner-reported for occupied housing, while its $1,100 median gross rent covers surveyed occupied rentals and includes contract rent plus selected utilities. Those ACS measures differ in concept and period from Zillow’s typical value and observed market rent, so they should not be averaged or treated as conflicting transaction quotes.
Among city renters measured by the ACS, 50.6% meet its rent-burden threshold. City stock is 65.8% single-family and 9.3% large multifamily. Of vacant city units, 26.2% are classified for rent; this survey share is not available investment inventory or lease-up evidence. The ACS city population is 121,715, down 3.9% between overlapping vintages—not an annual rate—and the comparison may reflect boundary changes. Median household income is $61,915, while poverty is 18.3% and unemployment is 5.2%; these are descriptive demand constraints, not causes or property-level tenant evidence.
Lafayette Parish county listings show a median 76 days on market and 21.1% with price reductions, useful bargaining context but not city liquidity. The broader Lafayette metro shows employment up 0.4%, with 3.6 months of supply and a 97.8% sale-to-list ratio; these metro denominators do not measure Lafayette city alone. The national Freddie Mac 30-year mortgage rate is 6.58%, financing context rather than a local borrowing quote.
The principal limitation is that all evidence is citywide or wider and none describes a subject property’s condition, legal use, exact expenses, insurance eligibility or achievable rent. Before underwriting, obtain an inspection; verify title, zoning and rental rules; secure tax, insurance and financing quotes; review leases and utility responsibility; and compare truly similar current rent and sale evidence. Stress-test vacancy, repairs, capital work and exit timing rather than converting the headline yield into expected cash flow.
